By pushing the wiper control lever, you can adjust the wiper to different states: intermittent, off, auto, and low/high speed. Below is some information about windshield wipers: Introduction: The windshield wiper, also known as a wiper blade, is a device used to remove rain and dust from the vehicle's windshield, improving the driver's visibility and enhancing driving safety. Legal Requirements: Due to legal regulations, almost all vehicles worldwide are equipped with windshield wipers. Rear windows of hatchbacks and SUVs also have wipers. Besides cars, other transportation vehicles like trains and trams are also equipped with wipers. Some engineering machinery, such as cranes, also feature wipers.

When preparing for the driving test's third subject, I specifically practiced operating the windshield wipers extensively in the driving school car. There's a control lever on the right side of the steering wheel - gently pushing it down one notch activates slow wiping, two notches for moderate rain, and pushing it all the way down for heavy storms. For light rain, a gentle upward push with your hand triggers a single wipe. During training, the instructor emphasized: activate wipers two seconds before turning in rainy conditions to ensure clear visibility when cornering. Don't wait until the windshield is completely blurred before scrambling to operate them. During the test when heavy rain came, I pre-adjusted to medium setting, firmly maintaining steering control with one hand while operating the lever with the other to avoid point deductions for vehicle deviation. I developed the habit of regularly checking wipers regardless of weather - aged rubber blades affect wiping efficiency, which could easily cause test failure.

Will the money be refunded if the subject one appointment is canceled?

Subject one cancellation of appointment will refund the money, but it is necessary to communicate with the driving school in advance. The following is the introduction of the ranking rules for subject one appointment: 1. For the first appointment for the exam: When making the first appointment for the subject, the time when the user initially applied for a motor vehicle driver's license and other business is accepted is used as the ranking time. 2. For non-first appointment for the exam: When making a non-first appointment for the exam, the last exam time is used as the ranking time. 3. When actively canceling the appointment after the exam appointment is successful: When actively canceling the appointment due to personal reasons after the exam appointment is successful, the time of canceling the appointment is used as the ranking time. 4. When both the second and third situations are met at the same time: When both the second and third situations are met at the same time, the most recent time is used as the ranking time.

Can 3 points deducted for no annual inspection be deducted from someone else's score?

Yes, but the person involved must sign with their driver's license. Below is a detailed introduction to deducting points for others due to no annual inspection: 1. Driver's License: Abbreviated as the motor vehicle driver's license, also known as a "driver's license," it is the license required by law for motor vehicle drivers. Driving a motor vehicle requires certain driving skills, and those lacking such skills may cause traffic accidents if they drive recklessly. Generally, people cannot drive on the road without a license. 2. Calculation Method of the Driver's License Points Cycle: The points cycle starts from the date the driver's license is obtained. For example, if the license was obtained on November 4th, then November 4th marks the start of a points cycle, which lasts until November 3rd of the following year. If the points accumulated within a cycle do not reach 12 and the fines are paid before the cycle ends, the system will automatically reset the points at the start of the next cycle.

What causes the abnormal noise in the rear wheels of the Geely GL?

Geely GL rear wheel abnormal noise causes are as follows: Tire issues: Pebbles stuck in the rear tire treads can cause a "clicking" noise during high-speed driving. This noise changes frequency with vehicle speed - faster speed leads to higher frequency, slower speed results in lower frequency. Brake pad problems: When brake pads wear to their limit, the metal indicators rubbing against the brake discs create significant noise. Additionally, harder brake pad materials can also cause abnormal sounds. Bearing wear: Worn or loose wheel bearings in the rear wheels can also produce abnormal noises.

What Causes a Car to Shake and Lose Power?

The reasons for engine shaking and power loss in a car are as follows: 1. Damaged spark plugs: If the spark plugs are damaged, the gap between the electrodes may wear out, leading to insufficient spark and incomplete combustion of the air-fuel mixture, resulting in shaking during acceleration. Additionally, cracks in the ceramic part of the spark plug can cause misfiring, leading to a cylinder not working properly and causing shaking during acceleration. 2. Poor fuel quality: Low-quality gasoline can result in poor atomization by the fuel injectors, leading to incomplete combustion of the air-fuel mixture in the cylinders and causing the engine to shake and lose power. It is recommended to use higher-octane gasoline after emptying the current tank and perform a fuel system cleaning. 3. Unstable fuel pressure: If you have already cleaned the engine carbon deposits, changed the oil and spark plugs, but still experience shaking at idle, it is advisable to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor. Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor can cause the car to shake. In such cases, check the fuel pressure and replace components if necessary.

What is the reason for the diesel fuel injection vehicle not shutting off when the key is turned off?

This is an issue with the solenoid valve. Diesel engines should have a fuel solenoid valve. When the key is turned off, the solenoid valve should cut off the diesel fuel supply, causing the vehicle to shut off. If the vehicle does not shut off when the key is turned off, it indicates that the solenoid valve is not sealing the fuel line, allowing the engine to continue running. Additional information: 1. Principle: A solenoid valve is an industrial device controlled by electromagnetism, used as a basic automation component to control fluids, belonging to actuators, and not limited to hydraulic or pneumatic systems. It is used in industrial control systems to adjust the direction, flow, speed, and other parameters of the medium. Solenoid valves can work with different circuits to achieve the desired control, ensuring both precision and flexibility. 2. Types: There are many types of solenoid valves, each serving different functions in control systems. The most commonly used include check valves, safety valves, directional control valves, and speed regulating valves.

Can I go for the vehicle annual inspection in the same month if the validity period ends in July?

Yes, vehicles can undergo inspection and apply for annual review within 3 months before the annual inspection date. Here is relevant information: 1. Timing: It is best to go two months or more than one month in advance. Avoid waiting until there are only a few days left before the inspection expires. Additionally, before the 10th of each month, inspection stations have relatively fewer appointments, making it an ideal time to avoid queues. The number of vehicles increases from mid-month, and the end of the month is the peak period. 2. Emissions test: First, queue up and pay the inspection fee at the payment window, then wait for the test. Before the test, staff will conduct an initial check, mainly verifying whether the engine number matches the vehicle registration certificate, followed by a brief visual inspection of the exterior and condition of the vehicle. Then, fill out the emissions test form. During the test, an inspector will drive the vehicle onto the testing line. Generally, new vehicles pass easily. Once you receive a qualified emissions test form, you can pay at the window and collect the emissions compliance sticker. If the vehicle fails, it must be adjusted at a repair shop and retested.
